Abstract: The subject matter of the invention is a luminous display device for optically displaying a multiplicity of information items on a display panel (1). This panel exhibits locations to be illuminated. The planar end of at least one optical fibre bundle is directed towards the rears of these locations. The other end of the bundle can be illuminated by a light source, the light of which, which is directed towards the end of the optical fibre bundle, is interrupted or released in dependence on the respective information. The display panel (1) is divided into segments (3, 4, 5, 6, 24) which can be mounted separately from one another. At the locations to be illuminated on the rear of the segments (3, 4, 5, 6, 24), recesses (7, 8, 9) are provided. The rear of the segments (3, 4, 5, 6, 24) is in each case covered by a light-scattering foil (11). The holders (21) of the optical fibre bundles (22) are arranged in recesses (16, 17, 18) of a plate adjoining the foil, the recesses of which extend to the foil (11) at the locations of the segments to be illuminated. <IMAGE>

The backing material (30) has an acoustic impedance lower than that of the piezoelectric material layer (10, 10a, 10c). Interposed between the backing material (30) and one electrode (11, 11a, 11c) is an acoustic reflecting material layer (50, 50a, 50b, 50c) which has a thick first portion and a thin second portion. The second portion may have a substantially zero thickness to allow the backing material (30) to be in partial contact with one electrode (11, 11a, 11c). Thereby, the ultrasonic probe (200) can transmit and receive ultrasonic waves at its resonance frequencies. Also provided is an ultrasonic diagnostic apparatus (FIGS. 15 and 16) which displays an image resultant from combining images having the frequencies obtained by driving the ultrasonic probe (200).

Abstract: A system for the control of a tractor implement hitch (10, 13) in response to a selected operating parameter such as hitch position or draft force. The system enables the desired value of the selected parameter to be set (S) and this desired value is compared in a first comparator (P, D) with the actual sensed value of the parameter to provide a first error signal (E). A velocity setting function (VS) is provided which sets a hitch velocity (v) relative to the tractor which is dependent on the magnitude of the first error signal. The actual hitch velocity is sensed and compared with the set velocity in a second comparator (V) to provide a second error signal. The system responds to the second error signal to control the position of the hitch so as to reduce the first and second error signals to zero.

Abstract: A load control device is provided with a throttle valve (9) determining the output of an internal combustion engine, which valve is rotationally fixed to a throttle valve shaft (32) supported in the throttle valve housing (30). In idling operation the throttle valve shaft (32) is controlled by an electric motor (14) and a post-connected four-bar linkage (16). This includes a pinion (14) arranged on the output shaft of the electric motor (14), which pinion meshes with a segment gear (50) which is drive-connected via a second linkage (53) to a rotor (54) driving the throttle valve shaft (32). Owing to the advantageous arrangement of the four-bar linkage (16) a very large transmission ratio can be obtained between the output shaft (40) of the electric motor (14) and the throttle valve shaft (32), so that it is possible to manage with a very small, cost-effective electric motor. <IMAGE>

Abstract: A digital arithmetic logic unit is described in which the carry chain (6) is subdivided into a series of bit-fields allowing independent and simultaneous data manipulation to be undertaken in each of the bit-fields. Division of the carry chain is achieved via a carry chain selector (7) consisting of a series of multiplexers (9), one being placed between each stage (FA) of the carry chain. Each multiplexer has two data inputs, one of which forms the carry to the next stage of the carry chain. The carry selected either continues the computation or defines the end of the bit-field and forms the least significant bit of the next bit-field. This selection of the carry by the multiplexer is under control of a programmable register (8), thus allowing variable division of the carry chain.

Abstract: A digital motion verification circuit (10) for a television system. The circuit synchronizes an actual and a stored signal from an edge motion indicator with the system clock (24), so that the edge signals are precisely timed and do not have errors from overlapping or mistimed signals. The circuit uses an EXCLUSIVE OR circuit (12) followed by an inverter stage (14) to produce an output when the clock synchronized stored signal and the actual signal have a discrepancy. This EXCLUSIVE OR output signal is applied to the data input of a shift register (16) that produces clock synchronized output signals which, when accumulated to a predetermined number, initiate a motion flag which indicates the presence of several exactly adjacent signals.

Abstract: Method of producing printing plates by means of a laser beam, said laser beam being scanned by means of a rotating polygonal mirror (32). According to the invention the rotational movement is transferred to the polygonal mirror (32) by means of a magnetic coupling, possible oscillations being dampened by a hysteresis-dampened, i.e. a faraday-dampened, mag­netic coupling. The magnetic coupling is formed by intermeshing, radially projecting members, which can be slightly rotated relative to one another and which comprise strong magnets (62) . The result­ing rotational accuracy is 6 ppm per rotation. In this manner it is possible to perform a laser scanning at a high speed while maintaining a high accuracy. The rotational shaft of the polygonal mirror (32) is disposed in an air bearing and comprises a cylinder (53) of a relatively heavy material, such as granite.

Abstract: A method and apparatus are disclosed for replenishing metal ions in an electrolyte depleted of the metal ions. A preferred example is replenishing tin in the electrolyte (14) of an electrolytic tinning apparatus having an insoluble anode (16) whereby the electrolyte becomes depleted of tin in the electrotinning process. The replenishment apparatus comprises an electrolytic cell (30) including a tin anode (56), a cathode (58), and an electrolyte chamber for the tin anode and the cathode. The cathode (58) is a gas diffusion electrode. An electrical circuit, usually having additional circuit resistance (92) but free of connection to an external power source, connects the anode to the cathode. The electrolyte chamber is in flow communication with the electrolytic tinning apparatus. The gas diffusion cathode (58) is exposed, on its gas side, to a source of gaseous reactant, eg. oxygen. When the anode and gas-diffusion cathode of the replenishment electrolytic cell are connected together electrically, a current flows between the anode and the cathode, without an external power source. The current flow is at a current density which is effective to dissolve the tin of said tin anode into the electrolyte.
